ScrollBuilder class

A builder widget that adds RefreshIndicator and Scrollbar to scrollable widgets.

This widget simplifies adding pull-to-refresh and scrollbar functionality to ListView or SingleChildScrollView. Perfect for list views with refresh capability and desktop/web scrollbar support.

Features:

  • Easy pull-to-refresh integration
  • Platform-specific scrollbar (desktop/web)
  • Automatic ScrollController management
  • Custom ScrollController support
  • Interactive scrollbar with visibility controls
  • Simple builder pattern

Example:

ScrollBuilder(
  onRefresh: () async {
    await refreshData();
  },
  showScrollbarWhenDesktopOrWeb: true,
  builder: (context, controller) {
    return ListView.builder(
      controller: controller,
      itemCount: items.length,
      itemBuilder: (context, index) {
        return ListTile(
          title: Text(items[index].title),
        );
      },
    );
  },
)

スクロール可能なウィジェットにRefreshIndicatorとScrollbarを追加するビルダーウィジェット。

このウィジェットはListViewやSingleChildScrollViewに プルトゥリフレッシュとスクロールバー機能を追加することを簡素化します。 リフレッシュ機能とデスクトップ/Webスクロールバーサポートを備えたリストビューに最適です。

特徴:

  • 簡単なプルトゥリフレッシュ統合
  • プラットフォーム固有のスクロールバー（デスクトップ/Web）
  • 自動ScrollController管理
  • カスタムScrollControllerサポート
  • 表示制御付きインタラクティブスクロールバー
  • シンプルなビルダーパターン

例:

ScrollBuilder(
  onRefresh: () async {
    await refreshData();
  },
  showScrollbarWhenDesktopOrWeb: true,
  builder: (context, controller) {
    return ListView.builder(
      controller: controller,
      itemCount: items.length,
      itemBuilder: (context, index) {
        return ListTile(
          title: Text(items[index].title),
        );
      },
    );
  },
